Internet Economics: Five factors that make the Internet different 1. Packet-switched network architecture ð Connection-less not connection-oriented 2. Pricing independent of distance & duration ð Average message covers 15 or more “hops” 3. Peering arrangements, not settlements ð Based on a full-circuit regime, not on half-circuits 4. Traffic flows highly asymmetric ð Dominant flow is to terminal that initiates a session (though this is changing …. ) 5. The United States sets the rules! ð There is no “Internet Telecommunication Union”
Internet telephony: Different modes l Computer to computer Since 1994 ð Conversation between two similarly equipped computer users via Internet Phone Gateway Computer l Computer to telephone Since 1996 Internet ð Internet user interconnecting with Public Telephone Network via an intermediary service provider (e. g. , call-back company) or a service provider’s Website Phone Gateway Computer Public Switch l Telephone to telephone Since 1997 ð Telephone carrier routes telephone or fax message via a data network (Internet, frame relay) rather than via the Public Telephone Network Phone Gateway Computer Telephone Internet Phone Gateway Computer Telephone Phone Gateway Computer Public Switch Telephone

Internet, price and service trends: Retail market l Until recently, flat-rate pricing dominant ð All you can eat for US$19. 95 l Now, “Free Internet” becoming highly popular ð Price of Internet access cross-subsidised by cost of local calls plus revenue drawn from advertising l Towards lower service quality ð “Best efforts” service delivery at lowest price l Cross-promotion of Internet and other services ð “Free PC” with three year’s ISP subscription l Tendency towards industry concentration ð AOL’s subscriber base > next ten ISPs added together
What makes the Internet so cheap? l Network externalities ð Interconnection of networks shares costs and builds economies of scale l Technical efficiency ð Packet switching, routing, statistical multiplexing l Piggybacking on Public Telephone Network ð Much of network investment already amortised ð Telephone network has built-in cross subsidies l Competitive network and service provision l Public policy subsidies (esp. in US) l No settlements between operators
Where does the money go? Typical Internet Service Provider cash-flow $19. 95 per month subscription $7. 50 -$10. 50 Wholesale Po. P Access $2. 00 - $3. 00 Customer Care $3. 50 -$7. 50 margin per customer $3. 00 amortized customer marketing Source: Adapted from Paul Stapleton, ISP$ Market Report, Boardwatch Magazine.
When is a local call not a local call? l Internet usage has grown fastest in countries which permit “free” or untimed local calls (e. g. , USA, Canada, HK, Australia) l But, PTOs claim that Internet users and ISPs are “free-riding” the network ð longer average sessions ð asymmetric traffic flows l In countries where local calls are metered, users complain that Internet is too expensive ð “Strikes” of Internet users in Germany, France l Rapid take-off of “Free Internet” ð Free monthly Internet access in return for loyalty to dial-up local loop service provider
Internet Service Providers do not pay usage-based access charges: ðUS access charge for telephony = US$0. 02 per min ðUS access charge for Internet = US$0. 0009 per min Tariff policy Internet users have no incentive to terminate or shorten calls: ðaverage length of telephony call = 5 -10 mins ðaverage length of Internet call = 20 -40 mins Usage patterns The Regulators’ dilemma Introduce usagebased access charges Risk political meltdown Do nothing Risk local loop meltdown
Settlements-based traffic PTO = Public Telecommunications Operator Delivers traffic PTO A Collects traffic Pays settlement fees Collects revenues User 1 User 2 User 3 PTO B Terminates traffic Retains revenues User 1 User 2 User 3 For accounting rate traffic, a direct bilateral relationship is established between the origin and termination operators. Intermediate transit operators are compensated from the accounting rate which is usually split 50: 50. PTO B retains net settlement. ……. . .

Settlements and sender-keepsall: What’s the advantage? l Settlement-payment traffic ð Transfers revenue from core to periphery of network ð Promotes “organic” network growth ð BUT, where traffic is unbalanced, leads to big deficits (e. g. , US$5. 7 bn deficit in US, in 1996) l Sender-keeps-all traffic ð No revenue transfers ð Promotes “spontaneous” network growth ð BUT, no incentive to carry traffic being transited or terminated Note: Where traffic flows are in balance, there is no practical difference
